How can I tell what kind of ink ribbon I need for an old typwriter?

The serial number is x-1453181 its a royal typwriter 1920’s- 1930’s. Please help!

admin answers:

Almost all manual typewriters use half-inch-wide ribbons, and these can still be found. (If you have an odd-sized ribbon, experiment with ribbons for computer printers, time clocks, cash registers, and other machines.) Most typewriters can use dual-color ribbons (red and black), so look for one of those — they look nice and can be useful. Good ribbons are still available from the sources listed below. Your local office supply store may also have ribbons for manual typewriters, and it may have ribbons intended for printing calculators which will work just as well. Ribbon spools (the reels) are slightly more challenging, if your typewriter is missing them. Ribbons are usually sold on plastic spools, and you may have to experiment with several kinds before you find one that fits your particular machine.

See link below for exact places that sell the ribbon that you need.

What is the best way to learn my times tables ?

This is really bad and embarrising but im now 15 nearly 16 and i dont know my times tables 🙁 im taking my gcse in november and need to get a c grade (or better !) but i really believe not knowing my times tables is really ruining my chances this 🙁 please please help as this is my last and only hope Thanks 🙂

admin answers:

Hello its really simple to do the times tables you have to think about them as ‚Number Sequences‘. If you like the explanation below I have a rather interesting conversion chart you may wish to have about metric litres.

Look but DONT TOUCH the second digit of a times table it is the holy grail and ‚tho shall not touch‘, only change the first digit – and you have learnt the tables

Here are the patterns:

There are nine numbers in the one times tables:

1,2,3,4,5,6,7,8,9

Learn the four numbers from the two times tables:

2,4,6,8,0

2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38

1. 10,12,14,16,18
2. 20,22,24,26,28
3. 30,32,34,36,38

I don’t like the three times table, its odd

3,6,9, – 2,5,8 – 1,4,7,0 37 x 11 = 407

Q. Which number is in the 11 times tables

306
902
206
506

A1. 902 – correct
A2. 506 – correct

902 subtract one from the hundred column 802 remove the zero 82 now check the answer by dividing 902 by 82 = 11

Problem 2: If a three digit number has a one in the middle?

Q1. Where is 616 in the 11 times table?

Unsolved: I’m not sure without a calculator, is it 66 ?

– Nope its not

Method 3: If the three digit number has tens column lower than the hundreds column?

The you must take away one from the hundreds and combine with last digit you get the number

Q. Where is 737 in the 11 times table?
Q2. Where is 616 in the 11 times table?

But now you know all the 11 times tables from 1 – 90 also take notice of how the numbers below are grouped. Unfourtantely this isn’t a complete understanding and memory is indeed needed.

Its now easier to work out the ‚possible‘ position of these numbers in the 11 times table, but you will not get 100% correct answers just by using those techniques above. But its a fuller picture we get of 11’s

How many ways can a test be filled out, if a student takes a 7 question true/false quiz and guesses?

i got 128 ways.

admin answers:

You are correct, it is 2 to the power of 7. It is called a permutation, and you simply need to know how many optional „answers“ are possible and how many „questions“ there are. Same thing as figuring out odds for things like the lottery. Good luck!

Here is a cool on-line calculator for this:

Nancy asks…

What is a fair price for a Harley Davidson Velo Glide Bicycle?

My wife and I are selling a hardly used Harley Davidson Velo Glide Bicycle. 4 Speed. This is in very good condition and was given to us 2 years ago but we never use it. Does anyone know what a fair price is? We were told it is very rare. Thanks!

admin answers:

They aren’t THAT rare. They were sold by GT (bicycle brand) dealers. The original list price was almost $2000. But were lax in sales so most of them saw a plunge to under $300 brand new. There are still a couple in the odd shop for sale as new bikes.

GT is owned by a company called Pacific Cycle who is the largest supplier of bicycles in the world. They own many brands and the Velo Glide was one of their attempts to secure licensing the H-D name.

Anyway, I suggest that you go to http://thecheapbikeshop.com and click on „Used Bike Value Calculator“, then fill out the form. It automatically determines a good sale price for you. I would use the „Actual Cash Value“ price when determining a fair price.

Also, since what was paid for the bike is sketchy, I would use the midrange „original price“ of $1000, and the model year of 1997.

EDIT: Just to clarify, the bikes were NOT made by HD, they were made for GT Bikes by Fairly Bicycle Manufacturing Company.
